Pipe repair clamp installation tool

ABSTRACT

A manually operated tool engages and draws towards one another opposed spaced flanges of a repair clamp disposed about a leaking pipe for securely maintaining the clamp in position on the pipe over the leak allowing plural nut and bolt combinations on the clamp to be tightened in sealing off the leak. A movable handle has attached thereto first and second pivoting arms adapted for respectively engaging a slot within the clamp&#39;s first edge flange and the outer edge of the clamp&#39;s second opposed edge flange when the handle is in a first non-use position. Moving the handle to a second use position urges the clamp&#39;s edge flanges toward one another drawing the clamp securely about the pipe, while still allowing the clamp to be moved along the pipe over the leak and plural nut and bolt combinations to be securely tightened in sealing off the leak.

FIELD OF THE INVENTION

This invention relates generally to fluid carrying conduits, or pipes,and is particularly directed to a leaking pipe and a tool forfacilitating the positioning of a repair clamp on the pipe for sealingoff the leak.

BACKGROUND OF THE INVENTION

Fluid carrying pipes are subject to leakage caused by damage ordeterioration over time. When the leak in the pipe is readilyaccessible, repairing the leak is fairly straightforward. However, whenthe leaking pipe is buried in the ground or is otherwise not readilyaccessible, it is frequently difficult not only to locate the leak, butto repair the pipe and seal off the leak.

Repairing a leaking pipe typically involves positioning a clamp over theleak. The clamp is slipped over the pipe and facing end portions of theclamp are tightly drawn together typically by nut and bolt combinations.The repair clamp is typically comprised of high strength steel and isfrequently difficult to position on the pipe and draw the opposed endsof the clamp together so that the clamp is securely positioned on thepipe because of the tendency of the clamp ends to pull away from oneanother due to tension in the clamp. This task also typically involvespositioning a gasket comprised of a suitable sealing material betweenthe fluid-carrying pipe and the repair clamp. This task is frequentlymade extremely difficult by leakage of the fluid from the pipe and mayeven be highly dangerous when dealing with hazardous materials. Inaddition, because of the difficulty in excavating around the pipewithout damaging the pipe, access to the leaking portion of the pipe istypically very restricted and this further complicates and renders moredifficult the task. Finally, because of the leaking fluid, theunderground location, and the structure of the repair clamp, the clampinstaller is subject to injury.

The present invention addresses the difficulties encountered in theprior art by providing a manually operated tool which facilitates thepositioning of a pipe repair clamp about a leaking pipe for sealing offthe leak. The pipe repair clamp installation tool can be operated withthe use of only one hand allowing the installer to use the other handfor proper positioning of the clamp on the pipe. Once the repair clampis properly positioned on the pipe, the installation tool securelymaintains the repair clamp in position over the leak allowing for thetightening of nut and bolt combinations which draw the clamp tightlyabout the pipe in sealing off the leak.

OBJECTS AND SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to facilitate thesecure positioning of a repair clamp on a leaking pipe allowing theclamp to be tightened to seal of the leak.

It is another object of the present invention to provide a tool whichfacilitates the positioning of a repair clamp on a leaking pipe and thetightening of the clamp over the leak to seal the pipe.

Yet another object of the present invention is to provide a manuallyoperated tool which tightens a high strength repair clamp on a leakingpipe, allowing the clamp to be moved in position over the leak andsecurely tightened to seal off the leak, followed by removal of the toolfrom the clamp.

A further object of the present invention is to facilitate installationof a repair clamp on a leaking pipe where only limited access to theleak is available such as in an underground pipeline.

This invention contemplates apparatus for installing a repair clamp on apipe, where the repair clamp includes a generally cylindrical bodyhaving first and second opposed edge flanges, a slot extending thelength thereof for receiving the pipe and positioning the repair clampabout an outer circumference of the pipe, and plural nut and boltcombinations coupled to the clamp's edge flanges for drawing the repairclamp tightly about the pipe. The apparatus comprises a body portionhaving first and second opposed ends; an arm having a first endpivotally coupled to the body portion intermediate the first and secondopposed ends thereof, the arm further including a second opposed endadapted for insertion in an aperture in the first edge flange of therepair clamp; and a clasp pivotally coupled to the body portion towardits first end and adapted to engage an outer edge of the repair clamp'ssecond edge flange when the body portion is in a first position relativeto the arm and clasp and the repair clamp is loosely disposed about thepipe, wherein pivoting displacement of the body portion about the armand clasp to a second position draws the repair clamp's edge flangestogether for securely maintaining the repair clamp on the pipe andallowing the nut and bolt combinations to be tightened for securing therepair clamp to the pipe in a sealed manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, there is shown a perspective view of one embodimentof a pipe repair clamp installation tool 10 in accordance with theprinciples of the present invention. A top plan view of the pipe repairclamp installation tool 10 is shown in FIG. 2, while a side elevationview of the pipe repair clamp installation tool is shown in FIG. 3. FIG.4 is an end-on view of the pipe repair clamp installation tool 10 shownin FIG. 3 taken along sight line 4—4 therein.

The repair clamp installation tool 10 includes a central body 12 havingdisposed on one end thereof a handle 14. The central body 12 includes apair of spaced, generally parallel arms 12 a and 12 b. Inserted throughand extending between the first and second arms 12 a and 12 b of thecentral body 12 are first and second pivot/coupling pins 20 and 22. Thefirst and second pivot/coupling pins 20 and 22 are securely connected tothe central body's first and second arms 12 a and 12 b. The repair clampinstallation tool 10 further includes a pivot arm 16 and an edgeengaging clasp 18. Pivot arm 16 includes a clamp end 16 a, a curvedcenter portion 16 b and a hook end 16 c. The clamp end 16 a of the pivotarm 16 is disposed about and attached to the second pivot/coupling pin22. The pivot arm's clamp end 16 a allows the pivot arm to freely pivotabout the second pivot/coupling pin 22. An edge engaging clasp 18 isdisposed about and pivotally coupled to the first pivot/coupling pin 20.In the configuration of the pipe repair clamp installation tool 10 shownin FIGS. 1-4, the curved center portion 16 b of the pivot arm 16 isdisposed upon a curved portion of the edge engaging clasp 18 which isdisposed about the first pivot/coupling pin 20. The hook end 16 c of thepivot arm 16 includes two 90° turns so as to form a step-likearrangement. As shown in FIG. 3, the distal end of the edge engagingclasp 18 includes a recessed slot 18 a which is adapted to engage anouter edge of an edge flange of a repair clamp is described below. Thetool's central body 12, pivot arm 16, edge engaging clasp 18, and firstand second pivot/coupling pins 20, 22 are preferably comprised ofhigh-strength steel. The tool's handle 14 is preferably comprised ofrubber or an elastomeric material to facilitate manual gripping andmanipulation. In the embodiment shown in FIGS. 1-4, the first and secondarms 12 a, 12 b of the tool's central body 12 extend into and aresecurely coupled to the tool's handle 14.

Referring to FIG. 5, there is shown a perspective view of the inventivepipe repair clamp installation tool 10 and the manner in which it isused to secure a repair clamp 32 to a leaking pipe 30. Repair clamp 32includes a generally cylindrical body portion 32 c having first andsecond opposed edge flanges 32 a and 32 b extending the length of therepair clamp. Each of the first and second edge flanges 32 a and 32 b ofthe repair clamp 32 is generally flat and is formed integrally with theclamp's body portion 32 c. Repair clamp 32 is shown disposed about apipe 30, with a liner 31 positioned between and in contact with theouter surface of the pipe and the inner surface of the repair clamp.Repair clamp 32 does not extend fully around the circumference of pipe30 and thus there is a gap between the clamp's first and second edgeflanges 32 a, 32 b. Inserted between the liner 31 and adjacent portionsof the inner surface of the clamp's body portion 32 c and spanning thegap between the clamp's first and second edge flanges 32 a, 32 b is aclamp insert 35. Clamp insert 35 has generally the same curvature as theclamp's body portion 32 c and extends the length of the repair clamp 32.The combination of the repair clamp's body portion 32 c and the clampinsert 35 engages the liner 31 about its entire outer circumference andmaintains the liner in intimate contact with the outer surface of thepipe 30 about the liner's entire inner circumference and length. Liner31 preferably has an elastomeric composition or is comprised of rubber.The pipe repair clamp 32 is preferably comprised of a high strength,corrosion resistant steel. The width of the gap between the clamp'sfirst and second edge flanges 32 a and 32 b is such that the repairclamp 32 may be easily slipped over the leaking pipe 30 being repaired.Thus, once the repair clamp 32 is disposed on the pipe 30, considerableforce must be used to draw the opposed first and second edge flanges 32a, 32 b of the repair clamp 32 toward one another to establish a sealedrelationship between the liner 31 and repair clamp 32 combination andthe inner fluid-carrying pipe. The inventive repair clamp 32 facilitatesthe application of this force in drawing the combination of the innerliner 31 and the inventive repair clamp 32 in contact with the outersurface of pipe 30 as described in the following paragraphs.

Attached to the clamp's first edge flange 32 a by means of respectiveweldments 54 a is a first pair of ribs 34 a and 34 b. A second pair ofribs 36 a and 36 b is similarly attached to the clamp's first edgeflange 32 a by means of weldments 54 b. Finally, a third pair of ribs 38a and 38 b is securely attached to the clamp's first edge flange 32 a bymeans of weldments 54 c. Similarly, attached to the clamp's second edgeflange 32 b by means of weldments 56 a, 56 b and 56 c are first, secondand third bolts 40, 42 and 44. The first bolt 40 is aligned with anddisposed between the first pair of ribs 34 a, 34 b which are attached tothe clamp's first edge flange 32 a. Similarly, the second and thirdbolts 42 and 44 are respectively disposed between and aligned with thesecond pair of ribs 36 a, 36 b and the third pair of ribs 38 a, 38 b.Each of the first, second and third bolts 40, 42 and 44 includes adistal threaded end portion which extends outwardly from the pair ofspaced ribs between which the bolt is positioned. A clamping bracket 46includes three spaced apertures each of which is adapted to receive thethreaded end of one of the first, second and third bolts 40, 42 and 44.Each of the threaded end portions of the first, second and third bolts,40, 42 and 44, is adapted to receive and engage a respective nut 50 a,50 b and 50 c. Tightening of the three nuts 50 a, 50 b and 50 c on thethree bolts 40, 42 and 44, respectively, moves the clamping bracket 46towards the repair clamp 32 and into contact with the distal ends of thethree pairs of ribs 32 a, 32 b and 36 a, 36 b and 38 a, 38 b, as shownin FIG. 6. Each of the paired ribs of the clamping bracket 46 and thethree nuts 50 a, 50 b and 50 c is preferably comprised of a highstrength, corrosion-resistant steel, as are each of the three bolts 40,42 and 44. Disposed between each of the three nuts 50 a, 50 b and 50 cand the clamping bracket 46 is a respective nylon washer 48 a, 48 b and48 c.

As shown in FIG. 5, the clamp's first edge flange 32 a is provided withfirst and second spaced slots, or eyes, 52 a and 52 b. Also as shown inFIG. 5, the hook end 16 c of the repair clamp installation tool's pivotarm 16 is inserted within the first slot 52 a within the clamp's firstedge flange 32 a. The pivot arm's hook end 16 c could as easily beinserted within the second slot 52 b within the repair clamp's firstedge flange 32 a for proper operation of the clamp as described below.With the hook end 16 c of the clamp's pivot arm 16 inserted within thefirst slot 52 a in the clamp's first edge flange 32 a, a slot 18 a inthe repair clamp installation tool's edge engaging clasp 18 ispositioned over and in contact with an outer edge of the repair clamp'ssecond edge flange 32 b. The distance between the first slot 52 a andthe outer edge of the clamp's second edge flange 32 b depends upon thesize of the clamp and the normal, unstressed distance between theclamp's first and second edge flanges 32 a and 32 b. The distancebetween the repair clamp installation tool's pivot arm hook end 16 c andits edge engaging clasp 18 may be adjusted by the orientation of thetool's central body 12 relative to the pivot arm's hook edge and thetool's edge engaging clasp. For example, rotating the combination of therepair clamp installation tool's central body 12 and handle 14 in thedirection of arrow 58 shown in FIG. 5 draws the pivot arm's hook end 16c and the tool's edge engaging clasp 18 toward one another. Similarly,rotation of the combination of the repair clamp installation tool'scentral body 12 and handle 14 in a direction opposite to that of arrow58 will cause increased separation between the pivot arm's hook end 16 cand the tool's edge engaging clasp 18 to provide increased spacingbetween the first and second edge flanges 32 a, 32 b of the repair clamp32. Once in the position shown in FIG. 5, the repair clamp installationtool 10 will remain in this position because it is attached to the pipeclamps edge flanges 32 a, 32 b.

Referring to FIG. 6, there is shown a perspective view of theconfiguration of the repair clamp installation tool 10 for drawing therepair clamp's first and second edge flanges 32 a and 32 b toward oneanother for reducing the size of the gap between these edge flanges andsecurely positioning the repair clamp 32 on pipe 30. In FIG. 6, therepair clamp installation tool's central body 12 and handle 14 have beenrotated in the direction of arrow 58 so as to be generally aligned withthe tool's pivot arm 16. Rotation of the tool's central body 12 in thedirection of arrow 58 reduces the separation between the pivot arm'shook end 16 c and the tool's edge engaging clasp 18 so as to drawn therepair clamp's first and second edge flanges 32 a, 32 b toward eachother, reducing the gap between these two edge flanges. This draws therepair clamp 32 and inner liner 31 more tightly about pipe 30. With therepair clamp installation tool's central body 12 in general alignmentwith its pivot arm 16, the repair clamp installation tool 10 maintainsthe repair clamp 32 in compression about the inner liner 31 disposed onthe pipe 30. The repair clamp installation tool's central body 12 willremain in the locked position shown in FIG. 6 without requiring theapplication of force to either the tool's central body 12 or its handle14. This allows the repair clamp installer to use both hands, ifnecessary, to properly position the clamp's clamping bracket 46 on thethree bolts 40, 42 and 44 and tighten the three nuts 50 a, 50 brespectively on bolts 40, 42 and 44. In order to release the repairclamp installation tool 10 from the repair clamp 32, the tool's bodyportion 32 c and handle 14 must be moved in a direction opposite to thatof arrow 58.

Referring to FIG. 7, there is shown a bottom plan view of anotherembodiment of a repair clamp installation tool 70 in accordance with theprinciples of the present invention. The repair clamp installation tool70 includes a central body 72 having first and second connected arms 72a and 72 b. Adjacent first ends of the first and second arms 72 a, 72 bform a handle 74. Adjacent a second end of the central body 72, thefirst and second arms 72 a, 72 b are arranged in a spaced manner and areconnected together by means of first and second pivot/coupling pins 80and 82. Repair clamp installation tool 70 further includes a pivot arm76 having a first clamp end 76 a disposed about and attached to thesecond pivot/coupling pin 82. A second, opposed end of the pivot arm 76is provided with a hook 76 c, while a curved center portion 76 b of thepivot arm couples the clamp end 76 a with the hook end. An edge engagingclasp 78 is disposed about and coupled to the first pivot/coupling pin80 disposed on a second end of the tool's central body 72.

Referring to FIG. 8, there is shown a sectional view of the repair clampinstallation tool 70 engaging a pipe repair clamp 90 in accordance withthe present invention. The handle 74 of the repair clamp installationtool 70 is formed by connecting adjacent portions of the tool's arms bymeans of a pair of coupling pins, or rivets, 84 and 86. In addition, thehook end 76 c of the tool's pivot arm 76 is inserted in a slot, or eye,92 within a first edge flange 90 a of a pipe repair clamp 90. Similarly,a slot 78 a within the edge engaging clasp 78 engages the outer edge ofthe second edge flange 90 b of the repair clamp 90. The repair clamp 90further includes a generally cylindrical body portion 90 c having thefirst and second edge flanges 90 a and 90 b. The orientation of therepair clamp installation tool 70 and relative position of its first andsecond pivot/coupling pins 80, 82 respectively coupled to the pivot arm76 and the edge engaging clasp 78 shown in FIG. 8 is such as to maximizethe distance “X” between the edge engaging clasp and the distal hook end76 c of the pivot arm. The orientation of the repair clamp installationtool 70 relative to the repair clamp 90 is such that the tool merelyengages the first and second edge flanges 90 a, 90 b of the repair clampwithout applying an inwardly directed force for drawing the two edgeflanges together. In order to apply a compressive force by the repairclamp installation tool 70 to the repair clamp 90, the tool's centralbody 72 must be rotationally displaced about the second pivot/couplingpin 82 in the direction of arrow 94 shown in FIG. 8. This results indisplacement of the repair clamp installation tool's pivot arm 76 in thedirection of arrow 96 and a narrowing of the gap between the repairclamp's first and second edge flanges 90 a and 90 b.

Referring to FIG. 9, there is shown a longitudinal sectional view of therepair clamp installation tool 79 taken from the direction opposite tothe sectional view of FIG. 8, wherein the repair clamp installation toolhas been displaced to the pipe engaging position. In the arrangementshown in FIG. 9, the distance between the repair clamp's first andsecond edge flanges 90 a and 90 b has been reduced to a distance “Y”,where Y<X, and the combination of the repair clamp 90 and a liner (notshown) securely engages the outer surface of a pipe (also not shown).
